long time ago i played on zx spectrum the boulder dash game and enjoyed it !
so why not for the oric atmos ?
here is my recreation of the game freely inspired from http://codeincomplete.com/projects/boulderdash/
from sources in js + some specs at http://codeincomplete.com/posts/2011/10 ... ulderdash/
i rewrote the game firstly in OSDK in c with asm routine for testing the rendering of the game... decoding the cave etc...
but it was so slow...so little by little i rewrite each "fat" C routine in asm
so speed is no more a problem for 1Mhz cpu !

now the game is fully completed and functionnal and optimized.
i started on winter 2015 holidays and wake up it on may 2016 still today

there could be have still some bugs ? let me know !
the sound engine is not fully complete (need more work on the sound fx)

i know the game is really hard , i dont even know how to finish some levels !

timing is very important on some levels
you can still choose different parameters
speed : less is the value, more is the wait at each frame
fps : is the number of frames needed for the timer to decrease 1 second

for keyboard handling i used the infamous peek(0x208)( and peek(0x209) for dead key)
i set the register 0x306 to 0x4000 (less interrupts and keyboard still readable)

may be a bad combination of both

on the lower right corner is the frame number
at each frame :
keyboard is read
game is updated
game is rendered

i 'd like to finish the sound fx which is still crappy for amoeba & magic wall sound
hopefully you can disable it by pressing the S key

for the source code i still have a lot of code cleaning to do, write more C to ASM, and not so much more time ... and summer is here

Just noticed a slight error on the title screen; the game was created by Peter Liepa but you've spelt it Lepia! Not important (might be to Peter... ) but probably worth amending if you ever release an updated version.

I really like the effect that happens when you switch between the birds-eye-view map and then rapidly into the game level .. this is a sort of polish not usually seen on an Oric game, and sort of makes the whole thing smooth, imho.

I ve just tried the game, it is beautiful but hard to play, I knew that a rock on another one could falling but not a rock on a wall. However this game is the first genuine version for Oric, at last ! Thanks Seb
